![]() ![]() ![]() RIB-treated seedlings exhibited higher biomass accumulation, higher Sodium (Na⁺) and Potassium (K⁺) concentrations in the roots, and higher K⁺ concentration in the leaf blades which led to lower Na⁺/K⁺ ratio in the leaf blades. Rice seeds were soaked in 10-μM RIB solution for 24 h, air-dried, and then the germinated seeds were cultivated hydroponically for three weeks under 25-mM NaCl to stimulate salinity stress prior to harvest. In the present study, we elucidated the role of riboflavin (RIB, vitamin B2) in ameliorating salinity stress in a well-known salt-sensitive rice cultivar (Oryza sativa L. However, such mechanisms are limited in sensitive rice varieties. Rice possesses well-developed mechanisms of managing excessive sodium concentration under salinity stress condition. ![]()
